Notes
setupString contains "key=value" pairs that dictate the behavior of the object. Keyname/values are separated by semicolons, and values (per keyname) are separated by commas. For example,
"key1=value1,value2,value3;key2=value1;key3=value1,value2;key4=value1"
To have a literal comma or semicolon inside one of the fields the must be escaped with the carot character.
- ^;
- ^,
For example key/value pairs see the Workplace Shell objects:
- WPColorPalette
- WPDisk
- WPFolder
- WPFontPalette
- WPKeyboard
- WPLaunchPad
- WPPalette
- WPPrinter
- WPRPrinter
- WPProgram
- WPProgramFile
- WPSchemePalette

All parameters have safe defaults. It is not necessary to pass unnecessary parameters to an object.
